Rayquaza is not obtainable anywhere in the region. However, if you have Pokemon Ruby, Sapphire or Emerald and you catch Rayquaza there: you are able to transfer it over from one of those games through Pal Park. Keep in mind that you must have beaten the Elite Four in Pearl, Diamond or Platinum;and you will have to transfer five other Pokemon along with Rayquaza to Pal Park; and those Pokemon can NOT know any HM moves whatsoever.You can choose any Pokemon you want. If you choose your strongest most powerful Pokemon, you may have to start your game over.YOU HAVE BEEN WARNED.
